Check Digit Verification of cas no

The CAS Registry Mumber 642089-50-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,0,8 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 642089-50:
(8*6)+(7*4)+(6*2)+(5*0)+(4*8)+(3*9)+(2*5)+(1*0)=157
157 % 10 = 7
So 642089-50-7 is a valid CAS Registry Number.

Synthesis of 2-(Diarylmethylene)-3-benzofuranones Promoted via Palladium-Catalyzed Reactions of Aryl iodides with 3-Aryl-1-(2-tert- butyldimethylsilyloxy)phenyl-2-propyn-1-ones

Lin, Chi-Fong,Lu, Wen-Der,Wang, I.-Wen,Wu, Ming-Jung

, p. 2057 - 2061 (2003)

3-Substituted-1-(2-tert-butyldimethylsilyloxy)phenyl-2-propyn-1-ones were coupled with aryl iodides by using palladium as a catalyst in ambient MeOH solution and gave 2-(diarylmethylene)-3-benzofuranones in moderate to good yields.
